1 Claim. (Cl. 116-116) This invention relates to new and useful improvements in speed indicators, and it has for its object to provide a kilometer reading on a speedometer made for mileage.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing, forming part of this specification, and in which similar characters of reference indicate corresponding parts, and in which:

Figure 1 is a front elevation of a speedometer.

Figure 2 is a side elevational view of the device shown in Figure 1.

Figure 3 is a side view, partly in section, showing the device connected for kilometer reading.

Figure 4 is a rear view of the device as shown in Fig ure 3, and

Figure 5 is a section taken on the line 6-6 in Figure 3.

Referring more particularly to the drawing and especially to Figure 3, the numeral 10 indicates a housing supporting the mechanism of a standard speedometer, a sleeve 11 extends from said housing 10 and abuts a sleeve 2,810,362 Patented Oct. 22, 1957 2 14 which surrounds the shaft 12 for a limited axial distance, said shaft 12 is integral with a gear 16; a coupling nut 13 secures the sleeve 11 and sleeve 14 together; said sleeve 14, which is integral with the plate 15, forms the housing 26.

The gear 16 meshes with a gear 17 also mounted in the housing 26; the said gear 17 is integral with the shaft 19, which is surrounded by a sleeve portion of said housing 26; a coupling nut 20 secures a drive cable sleeve 21 to the shaft 18, and the core 25 of said drive cable extends within the shaft 18.

The indicator shown in Figure 1 will register on the dial for mileage and on the dial 24 for kilometer.

I claim as my invention:

A device for providing a kilometer reading on a speedometer made for mileage and comprising, a housing, a shaft connected to a speedometer arranged in said housing, a first sleeve extending from said housing, a second sleeve surrounding said shaft a limited distance and abutting said first sleeve, a coupling nut securing said two sleeves together, a first gear integral with said shaft and being mounted in a casing, a second gear disposed in said casing and meshing with said first gear, said second sleeve being integral with the casing, a third sleeve, a second shaft surrounded by the latter, said second shaft engaging a drive cable, a cable core within said drive cable, and a second coupling nut securing said cable core to said third sleeve.
